Abstract: A mailer blank adapted to be folded into a mailer has front and back sides and adhesive bands on the front side and on the back side for securing the blank in its folded configuration. At least one of the adhesive bands on the front side is aligned with at least one of the adhesive bands on the back side, the aligned adhesive bands on the front side and on the back side comprising a series of spaced shaped patches. The patches comprising the adhesive band on the front side are shaped and spaced with respect to the patches comprising the adhesive band on the back side that when the mailer blanks are stacked one on top of the other, the patches comprising the adhesive band on a side of the mailer blank do not align with the patches comprising the adhesive band on the opposite side of the adjacent blank.
